Senior Software Engineers must have strong communication skills for socializing plans and potential solutions and working toward well-specified product behaviors.


Qualifications and Educational Requirements:

  • Required qualifications:
    o U.S. Citizen (position entails access to Controlled Unclassed Information).
  • Typical qualifications:
    o Bachelor's or Master's degree.
    o 8+ years relevant industry experience
    o Able to obtain DoD security clearance.


Required Skills:

  • Exploring code repositories to understand how existing features have been implemented.
  • Updating code to address defects, or to create new capabilities.
  • Designing and implementing new features.
  • Writing documentation for users or maintainers.
  • Writing automated tests.
  • Learning new technologies.
  • Researching technologies for potential adoption.
  • Communicating clearly and efficiently around all of the above.
  • Collaborating productively with stakeholders and other engineers.
  • Providing field engineering support for R&D, new product testing, and deployed systems.
  • Expertise in at least two software languages enumerated under "preferred skills".


Preferred Skills:

  • Git / GitLab
  • CI/CD
  • Python
  • Bash
  • Linux
  • Data visualization
  • C
  • C++
  • Rust
  • Docker
  • Networking
  • Experience working with or developing for DoD customers.


Physical Requirements/Working Conditions:

  • Ability to travel to Groton HQ on short notice.
  • Hybrid expectation: 100% onsite at Groton HQ for initial onboarding, and 2-3 days per week onsite thereafter.


Travel Requirements (If Applicable):

  • Occasional travel for at-sea support or major client milestones.
